when i try to go on Windows live i.d I enter my email add. & password; it replies ' Your already signed in with us, just sign in. when i try again, it says invalid id& password. vicious circle.Im confused. Do i need live i.d to chat?r they all afiliated, or supposed 2b. Even when i try to ask... they say sign in, and round and round it goes. Can I cancel Live I.D. portion, without jeopardizing my E mail, Messenger, Yahoo and rogers account
